IMPROVED FLUlDnNlETER.

Specification forming part of Letters Patent No. 1212127, dated April :21, 1857.

To all whom it may concern.;

Beit known that I, SAMUEL J. BURR, of the city of Brooklyn, county of Kings, and State of New York,y have invented a new and useful Machine for Measuring Gas,Vater, and other Fluids; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making part of this specification, inrwhich like letters refer to like parts, and in which- Figure l is an end view. Fig. 2 presents a view of the valves, valvestem, feed and discharge pipes. Fig. 3 is a perspective view of the inside of the valve. Fig. 4 is a top view of the valve, valve-stem, feed-pipe, and plate. Fig. 5 is a view of the end of the valve-stem adapted to be operated upon by the valvethrow. Fig. 6 is aview of the lever, its load, and pin, constituting the valve-throw. Fig. 7 is a view ol' the shifter, shaft, hollow tube, and arm. Fig. 8 is a transverse section showing the fiexible partition and its carrier (the shifter) thrown toward the right. Fig. 9 is a longitudinal and sectional view.

A and B represent the two sides or halves of the meter-box. D is the plate by which the valves are attached to the meter-box. E is the barrel covering the valves; G, entrance or inlet pipe; H, the discharge-pipe; J, the valvestem; K, the load of L the lever; M M, arms permanently attached to the shaft c, which runs through the tube f, and operated by the shifter O to change the valves; N N, ends of arms M M,which may be bent, if so required. O is the valve-shifter, also permanently attached to the shaft c and placed between the two portions of the flexible partition; R, the level-pin. t is the single opening or entrance through tothe valve 5 and U U are double openings or discharges between the valves and the apartments of the meter-box, one opening communicating with one apartment and the other with the other. V is a piece attached to the end of the valve-stem J, having slot a adapted to the reception of 4the pin R of the valvethrow @,the slot j ust described; b b,the two portions of the flexible partition, between which is placed the shifter O. c is the shaft, attached to which are the arms M M and the shifter O. d is the point at which the shaft a is attached tothe register. f is the hollow tube inclosing shaft c, either made in two pieces orin one piece, slotted in the center to receive the end of shifter O, through which the shaft c passes. Said tube is packed on its outer surface by the edges ofthe flexible partitions, which are placed between it and the walls of the meter-box, protecting shaft c and end of shifter O from contact with the packing, allowing them to work easily.

Operation: The duid to be measured enters at G, passes through E into the single opening t, which opening is turned to and fr0, so as to connect alternately with each of the double openings U U. Say (as the arrows point in the drawings) it takes the left-hand passage. (See Fig. 8.) Hence it passes between the flexible partition and the left-hand wall of the meter-box, and as the side A is filled the duid presses the flexible partition (by its own force and without the use of any springs or levers) as close to the right-hand wall of the box as desired, as seen at b, filling the whole space in the entire box, while the fluid in the rightf hand side is forced by the same pressure through the right-hand passage U and out at the discharge H. The shifter O, lying between the two portions of the partitions, is forced over (by the same power) with the partition, turning the shaft c, to which it (shifter O) is attached, and which shaft carries the arms M M, and they turn the valvethrow L, and when shifter O reaches the opposite wall of the box it changes the position ofthe single opening T and the double openings U U, reversing the course of the entering and escaping iiuid. To understand this better, look first at Fig. 7, and it will be seen that the shifter O is permanently attached to the shaft c, and (see Fig. l) the same shaft c has permanently attached to it the arms M M. As shifter O is raised from its reeumbent position it carries with it the shaft and arms, and when the end of the arm reaches the lever L the latter is also raised until it gets just beyond the center, when it falls by its own weight suddenly tothe other side and changes the position of the openings by means of the lever-pin R, Fig. 6, which pin plays in the slot of the end piece of the valve-stem that runs through the cock and changes the open ing from side to side.

I claim-a L.

1. The combination of the fiexible partition with shifter O, for the purpose of opening and closing the valves or apertures tov admit and discharge the fluid, so that the apartments shall be alternately filled and emptied, in the particular manner described and shown.k v

2. The combination of the valves, tube, and exible partition, substantially as described, 'so as to make the entering` fluid discharge the fluid (alternately) in each apartmentby its pressure upon the opposite sides of the iexible partition.

3. Shifter O, whether as set forth or in any other forni producing the same result, and

4. The combination of the shaft c, inelosed in the tube f with the valve-throw, substantially as described, and for the purpose set forth.
